OCZ Vertex 4 256GB Review

Testing:

Crystal Disk Mark 3.0: Crystal Disk Mark is a hard drive benchmark designed to measure the read and write speeds of drives by using 4k blocks, 512k blocks, and sequential data. For the test, we chose the 1000MB option.

In this test you start to see where the performance was mapped for the Vertex drive. The Everest 2 controller shows significant performance advantages in the write testing where it is the highest performing drive in all four tests. This test is meant to test both compressible and incompressible data streams and shows that the Vertex 4 handles these loads better than the competition, especially at higher queue depths.
